Is Vulcanus safe and trustworthy?

tashan scores Vulcanus on public evidence — tashan score 54.0/100, it is currently active, note: a single primary maintainer (bus-factor risk), no known advisories against the current release. Audit scope: OSV advisories, install-time scripts, build provenance and declared permission surface. We do not review source code or execute the capability.

How do I install Vulcanus?

In Claude Code: run `claude mcp add vulcanus -- npx -y @sunsato/vulcanus`. In Cursor / Claude Desktop, add it to mcp.json / claude_desktop_config.json.

Security audit

Every finding is shown in full — which advisory, the version that fixes it, and the exact command run at install time. Nothing in this audit is behind a licence.

No known advisoriesclearchecked against OSV for 0.4.4 — this package, not its dependency tree

No access inferred from declared dependenciesnothing it depends on reaches files, shell or network. This reads declarations only — built-in APIs are invisible to it, so absence of a declaration is not absence of access

Signed build provenancepublished from public CI with an attestation

You searched for one. Check the rest of your stack:

npx tashan-cli doctor

Reads the config already on your machine and names what is dead, deprecated or running code at install time. No account, nothing uploaded.
